Multi-stop-point single-slide-way sliding groove structure

Abstract

The invention discloses a multi-stop-point single-slide-way sliding groove structure. A first step (10) is arranged in an inner circle slide way (3), the direction of the side vertical face of the first step (10) is opposite to the tension direction of a spring, and the inner circle slide way (3) is connected with an outer circle slide way (4) through a sliding-out slide way (5) on the side vertical face of the first step (10). At least two second steps (9) are arranged in the outer circle slide way (4). The side vertical face of each second step (9) is parallel to the tension direction of the spring. At least two stop grooves placed between the inner circle slide way (3) and the outer circle slide way (4) are further formed in a spring box (2) and are connected with the inner circle slide way (3). Joint steps (11) are arranged beside the stop grooves. The slope of each joint step (11) is connected with the outer circle slide way (4), and the lower portion of each joint step (11) is connected with the corresponding stop groove. The multi-stop-point single-slide-way sliding groove structure can well avoid misoperation of a user in the using process, and enables pulling recovery to be smooth.

Description

technical field [0001] The invention relates to a chute structure, in particular to a multi-stop-point single-slideway chute structure. Background technique [0002] China with the publication number 203667736U discloses a self-locking and self-releasing take-up device for financial equipment, wherein: figure 1 It is a schematic diagram of a slideway single cycle of the utility model whose publication number is 203667736U. figure 2 It is the double circulation schematic diagram of the slideway of the utility model whose publication number is 203667736U. When the utility model is in use, a clockwork spring with counterclockwise tension is installed in the clockwork spring box 2, and the clockwork spring box 2 is hinged on the base plate, and the inner ring with a rectangular cross section is added to the clockwork spring box 2 to slide Road 3 and outer ring slideway 4, the inner ring slideway 3 and outer ring slideway 4 make the movement of the rotating link pin moving on ...

AI Technical Summary

Problems solved by technology

[0004] 1. The outer diameter of the barrel is Φ60. Calculated on the basis of a 1.2-meter telephone microphone line, the barrel can only accommodate 5 turns of the microphone line. Due to the height limit of the barrel, the microphone lines will overlap and overlap. When the microphone line overlaps, it is difficult to pull and recover

[0005] 2. When the utility model with the publication number 203667736U uses the single cycle of the slideway, since there are only 5 turns of microphone wires at the barrel, it can only provide at most 5 stop points

Due to improper use by the user, it is easy to cause the microphone cable to stop again. After the stop is not achieved, pull it out, that is, the function of automatic unlocking

[0006] 3. The outer diameter of the barrel is Φ60. Because the microphone wire is wound tangentially on the barrel, and because the force arm is too small, the initial pulling force required for pulling is relatively large, resulting in excessive pulling force of the microphone wire.
